Predictive capacity of adapted MEWS, qSOFA and UVA scores

	Adapted MEWS* >4	qSOFA ≥2	UVA >4
Unadjusted
Sensitivity	50.4	24.8	28.2
Specificity	74.9	90.4	91.1
Positive predictive value	30.7	36.2	41.2
Negative predictive value	87.2	84.5	85.2
OR (95% CI)	3.04 (2.01 to 4.59)	3.10 (1.86 to 5.15)	4.04 (2.44 to 6.67)

*The adaptation to the MEWS score pertains to the altered mental status score. In the original MEWS, 0 point was assigned for alert patients, 1 if they reacted to voice, 2 if they reacted to pain, and three if they were unresponsive. In our adapted MEWS, we assign 0 point for an alert patient and 2 for a patient with any altered mental status.

MEWS, modified early warning score; qSOFA, quick Sequential (Sepsis-Related) Organ Failure Assessment; UVA, Universal Vital Assessment.
